Hi, I am stuck on the exercise “Modifying each element in a list in a function”, could some one help me please?
Create a function called double_list that takes a single argument x (which will be a list) and multiplies each element by 2 and returns that list. Use the existing code as a scaffold.
You can place the code on lines 3 - 5 inside a function definition. You will need to change the n[i]s in the for loop to x[i]. Make sure to indent properly!
Error message I get:
double_list([0, 1]) returned [0, 1] instead of [0, 2]
n = [3, 5, 7] def double_list(x): for i in range(0, len(n)): x[i] = x[i] * 2 return x print double_list(n)
